Anterior cruciate ligament (ACL) graft failure is a difficult complication after ACL reconstruction (ACLR) surgery with risk factors that include patient characteristics and surgical factors. Analyzing and incorporating these risk factors into shared surgical decision-making is an important part of preventing complications after ACLR and revision ACLR. There is a growing body of literature studying the importance of patient anatomical factors that can predispose to risks of ACL graft failure and smaller lateral-to-medial tibial plateau ratio is an anatomical factor that is correlated with a higher risk of ACL rupture and ACLR graft failure. While further study and statistical analysis will be important in allowing surgeons to incorporate this risk factor in surgical decision-making, it shows promise as something to consider in the future.
